Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a rope end fixing device with rope break protection and anti-slanting function. Background Art

[0002] The lifting equipment starts a vertical or vertical and horizontal working stroke after picking up the materials, unloads after reaching the destination, and then travels empty to the material picking location, completing a working cycle, and then performs a second lifting or transportation.

[0003] The existing technology, the rope of the existing technology can only be used to detect whether the weight is overweight, but cannot detect the problem of oblique pulling, so in the actual use process, there are many accidents caused by oblique pulling.

[0004] Therefore, it is necessary to design a rope end fixing device with rope break protection and anti-slanting function to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a rope end fixing device with rope break protection and anti-slanting function, so as to overcome the above-mentioned shortcomings of the current prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A rope end fixing device with rope break protection and anti-oblique pulling functions, comprising a rope end fixing hanger, a balancing arm installed in the rope end fixing hanger through a balancing arm rotating shaft assembly, and wedge-shaped joints installed on the left and right sides below the balancing arm through pins, characterized in that: the balancing arm rotating shaft assembly comprises a self-lubricating bearing placed in the center position of the balancing arm, a self-lubricating gasket arranged at the shaft end of the self-lubricating bearing, and a balancing arm rotating shaft passing through the self-lubricating bearing, the front and rear ends of the balancing arm rotating shaft are both passed through the rope end fixing hanger, and buffer elastic sleeves are arranged on the left and right sides of the balancing arm, the buffer elastic sleeves are placed on the swinging stroke of the balancing arm, and the buffer elastic sleeves on the left and right sides are symmetrically arranged, and sensor shafts are arranged in the buffer elastic sleeves.

[0008] Preferably, a slot is provided at the bottom of one end of the balancing arm shaft, a fixing plate is installed in the slot, and the fixing plate is fixed to the side of the rope end fixing hanger by bolts, and one side of the fixing plate is attached to the side of the rope end fixing hanger.

[0009] Preferably, a hanger fixing shaft is respectively provided on the left and right sides of the rope end fixing hanger, and the hanger fixing shaft penetrates the rope end fixing hanger and is partially protruded.

[0010] The beneficial effects of the utility model are as follows: the technical solution provides buffer elastic sleeves on both sides of the balance arm shaft assembly, and the sensor shaft is placed in the buffer elastic sleeve. If the sensor shaft contacts the buffer elastic sleeve, the balance arm is limited to rotate, so that the unbroken wire rope can maintain the state of the sling without tilting, ensuring normal use. At the same time, the sensor sends a signal to cut off the rising circuit, so that the sling can only be lowered to the ground for maintenance work, and can prevent oblique pulling action, with high safety and double protection.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0017] Reference Figures 1 to 3A rope end fixing device with rope breaking protection and anti-slanting function, comprising a rope end fixing hanger 1, a balancing arm 3 installed in the rope end fixing hanger through a balancing arm rotating shaft assembly 2, and wedge joints 4 respectively installed on the left and right sides below the balancing arm through pins;

[0018] The balancing arm shaft assembly 2 includes a self-lubricating bearing 21 disposed in the center of the balancing arm, a self-lubricating gasket 22 disposed at the end of the self-lubricating bearing, and a balancing arm shaft 23 passing through the self-lubricating bearing, and both front and rear ends of the balancing arm shaft pass through the rope end fixing hanger;

[0019] A slot is provided at the bottom of one end of the balance arm shaft, a fixing plate 24 is installed in the slot, and the fixing plate is fixed to the side of the rope end fixing hanger 1 by bolts 25, and one side of the fixing plate is attached to the side of the rope end fixing hanger 1.

[0020] A buffer elastic sleeve 5 is provided on both the left and right sides of the balance arm. The buffer elastic sleeve is placed on the swing stroke of the balance arm, and the buffer elastic sleeves on the left and right sides are symmetrically arranged with each other, and a sensor shaft 51 is provided in each of the buffer elastic sleeves;

[0021] In order to facilitate the installation of the entire rope end fixing hanger, a hanger fixing shaft 6 is respectively provided on the left and right sides of the rope end fixing hanger, and the hanger fixing shaft penetrates the rope end fixing hanger and is partially protruded;

[0022] In this implementation case, when one of the wire ropes breaks, the balance arm rotates and contacts the buffer elastic sleeve, and the sensor shaft limits the rotation of the balance arm, so that the unbroken wire rope can maintain the state of the sling without tilting, ensuring normal use. At the same time, the sensor sends a signal to cut off the rising circuit, so that the sling can only be lowered to the ground for maintenance; similarly, when there is an oblique pull action during use, the rotation of the balance arm will also trigger the sensor to send a signal, prohibiting the lifting mechanism from rising and only allowing it to descend, thereby preventing oblique lifting.

[0023] The utility model is beneficial in that the technical solution provides buffer elastic sleeves on both sides of the balance arm shaft assembly, and the sensor shaft is placed in the buffer elastic sleeve. If the sensor shaft contacts the buffer elastic sleeve, the balance arm will be restricted from rotating, so that the unbroken wire rope can maintain the state of the sling without tilting, ensuring normal use. At the same time, the sensor sends a signal to cut off the rising circuit, so that the sling can only be lowered to the ground for maintenance work, and can prevent oblique pulling action, with high safety and double protection.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
